Application of CW-CRDS to Monitor and Control Chemical Vapor Deposition

July 1, 2000
Author(s)
David S. Green, J P. Looney, G W. Rubloff
Continuous wave excitation cavity ring-down spectroscopy (CW-CRDS) is being evaluated for real time chemical sensing of volatile CVD byproducts (e.g. HF, H2O) and as a quantitative and robust metrology tool for advanced process control methodologies.

New Low-Index Liquid Refractive Index Standard: SRM 1922

June 1, 2000
Author(s)
Jennifer R. Verkouteren, Stefan D. Leigh
A new standard for the calibration of refractometers has been developed. Standard Reference Material (SRM) 1922 is a mineral oil with a refractive index n D=1.46945 at 20 C, which is within the range of the Brix scale (% sucrose). The change in index with

Excited States at Surfaces: Fano Profiles in STM Spectroscopy of Adsorbates

March 1, 2000
Author(s)
John William Gadzuk, M Plihal
The Fano-Anderson model for a discrete state embedded within a continuum is revisited within the context of excitation and decay processes which lead to some manifestations of Fano lineshape profiles. The phenomenon of resonance tunneling between an STM
